One of my views is a UITableView which acts as the delegate for an AVAudioPlayer and this table essentially plays sounds when you select a certain row with options to repeat the sound after its finished playing. However, I noticed that if I select a cell with repeat ON for a certain sound and then scroll through the UITableView to sel...
My mp3 playing code is: NSError *error; soundObject = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:audioPathString] error:&error]; if (soundObject == nil) NSLog(@"%@", [error description]); soundObject.delegate = self; soundObject.numberOfLoops = 0; soundObject.volume = 1.0; NSLog(@"about to play"); [soundObject p...
Hi all, I am trying to use AVAudioPlayer to play some sounds in quick succession. When I invoke the sound-playing function less frequently so that the sounds play fully before the function is invoked again, the application runs fine. But if I invoke the function quickly in rapid succession (so that sounds are played while the previous so...
I have a library of 16 short sound clips I need to be able to play in quick succession. I realized that creating and preparing AVAudioPlayer objects in real time was too much to ask of the iPhone. So instead, during my app's initialization, I am pre-creating a series of AVAudioPlayers so that each one is basically pre-loaded with one...

I tried to search for sample code but no luck. Can anyone help showing me how to enable AVAudioPlayer for background playing in iOS 4? thanks. ...
Hey guys, I'm experiencing an odd problem with AVAudioPlayer class. Everytime I try to access one of it's properties they are null. // Get the file path to the song to play. NSString *filePath = [[[NSBundle mainBundle] pathForResource:pSound.fileName ofType:pSound.fileType] retain]; // Convert the file path to a URL....
I have a sound file I play using AVAudioPlayer. Simultaneously I record using AVAudioRecorder, both at 44.1kHz. I prepare the player/recorder, call play/record one right after the other, and have the recorder stop when AVAudioPlayers delegate audioPlayerDidFinishPlaying is called. When I look at the recorded audio file I see the recordi...
Hi, What is the difference between OpenAL and AVAudioPlayer on the iPhone? It seems that both can be used for playing/recording audio. When would you use either? What advantages/features does each provide? Thanks! -MT ...
I just installed an app I'm building on my iPhone 4, and even though the sounds I'm using play in the simulator, they don't play on the phone. Just using an AVAudioPlayer object for all the sounds that need to play when a user interacts with the app. ...
The documentation is rather poorly written when talking about playing audio in the background. It gives the impression that all you have to do to continue playing the audio that you are currently playing is to just add a key/value pair to the info.plist file and wallah, it's magic. However, this is not the case. For instance, if I pla...
I am developing a audio player in flex. I need a seekbar kind of like on youtube's video player. To implement the basic seek functionality the HSlider component is enough. But I also want to show the stream progress on the seek bar. (youtube colors the already streamed part of the seekbar red). Is there a way I can achieve the same? I a...
I have added the UIBackgroundModes property in Info.plist to have an array entry of "audio" and have added the call to setup the audio session: [session setCategory: AVAudioSessionCategoryPlayback error: &error];. However, the only test device I have is the iPod Touch 2G which doesn't support multitasking. I've tried the simulator but ...

I unsuccessfully tried to implement a playback audio that continues to play in background by setting the UIBackgroundModes property and by activating an audio session as Joshua Weinberg suggested, but it doesn't work on the simulator and I have no chance to test on a device with iOS4. I read about of a possible issue with the simulator, ...
